I'm having trouble adding a non-certified channel to my device for testing purposes. I've already enabled it for all countries, including "Rest of the world". But when I try to add it I'm getting an error message stating "The channel code provided is associated with a channel not available in your region". Then I tried to reach Support (https://developer.roku.com/contact
) and filled out the form, but was unable to submit it. The error dialogue message didn't say much, apart from the generic statement "Oops! Something went wrong, please try again". Status code: 400.
